Abstract
Description
- Exemplary embodiments of the present invention relate to a body component, in particular a column for the motor vehicle.
- Body components in so-called monocoque construction have many uses in the construction of motor vehicles, in particular for columns and carrier parts, as well as for doors, flaps or similar. German patent document DE 10 2004 012 399 A1 discloses a vehicle column in monocoque construction. Here, the column comprises an outer shell and an inner shell, which are connected to each other via respective flanges and enclose a hollow space between them. In order to give the body the necessary stability both under normal operating loads and in the case of a crash, an additional reinforcement sheet is arranged in this hollow space. Disadvantageously, such multi-part sheet constructions are, however, particularly heavy, such that with the overall weight of the motor vehicle, the fuel consumption thereof, and thus exhaust emissions, also increase.
- German
patent document DE 10 2007 010 341 A1 describes a component in monocoque construction, in which the reinforcement element between the outer and inner shell is produced from a fiber composite plastic in order to save weight. Here, the reinforcement element is adhered to the shell. Weight can hereby be saved; the adhesion, however, increases the process time due to the setting requirements. Due to the adhesion, the structural element is also connected unreleasably to the shells. - Exemplary embodiments of the present invention are directed to a body component according that is particularly light, simple and quick to produce, as well as simple to repair.
- Such a body component, in particular a column, for a motor vehicle comprises an inner shell and an outer shell made from a metal, which are connected to each other in respective flange regions and which enclose a hollow space between them. A reinforcement element having a basic body made from a fiber composite plastic is arranged in this to strengthen the body component. According to the invention, the reinforcement element comprises at least one metallic insert, by means of which the reinforcement element is connected to the inner and/or outer shell. In other words, the joining location of the reinforcement element to the shells of the body component is a metal-metal connection. Thus, an adhesion can be dispensed with and simultaneously, a more stable, reversible connection, for example by screwing or similar, can be enabled. Such a body component is therefore both particularly light and particularly procedurally reliable and quick to join and simple to repair.
- In a preferred embodiment of the invention, the reinforcement element comprises two metallic inserts, which are connected to the inner and/or outer shell in the flange regions. In other words, such a reinforcement element extends transversely through the entire hollow space and connects the two flanges between the shells to each other, wherein respective metal-metal connections are provided on both connection sides. A particularly good level of stability is hereby achieved, wherein the advantages referred to above are maintained.
- The inserts are preferably formed as sheet metal, which can be simple metal strips or also transformed sheet metal constructions. In both cases, the production of the inserts, as well as the connection thereof to the fiber composite plastic, can be carried out particularly simply and cost-effectively.
- An example of this is the overmolding of the inserts with the fiber composite plastic, wherein at least one through opening or a similar positive-fit element is expediently provided in the inserts in order to ensure a stable and reliable interlocking between the plastic matrix and the insert part. As well as the simple overmolding, other methods are obviously also conceivable. For example, the insert parts can also be embedded into the reinforcement element in the course of resin transfer molding or during production of the fiber composite component in the course of a sheet molding compound process.
- Expediently, the reinforcement element has further reinforcement fibers made from a metal. These extend expediently through the entire body of the reinforcement element, in order to give this particularly high strength.
- Simultaneously, the provision of such metal reinforcement fibers enables a subsequent connection of the inserts to the reinforcement element, for example by welding or soldering, such that the inserts do not have to be embedded fixedly into the plastic matrix. The reinforcement fibers can also be overmolded in a simple manner with the fiber-reinforced plastic or, however, can be connected to the plastic matrix in the course of resin transfer molding or the production of a sheet molding compound.
- In a further embodiment of the invention, the reinforcement element has a substantially S-shaped cross-sectional profile. Hereby, it can be supported on the shell inner walls by its plastic region and thus ensures particularly good strengthening, wherein the soft support simultaneously prevents potential flapping during movements of the reinforcement element.
- Below, the invention and its embodiments are explained in more detail by means of the drawing. Here are shown:
-
FIG. 1 a sectional depiction through an exemplary embodiment of a body component according to the invention and -
FIG. 2 a side view of a reinforcement element for an exemplary embodiment of a body component according to the invention. - A column, referred to by 10 throughout, for a motor vehicle comprises an
outer shell 12 and aninner shell 14, which are produced from steel or aluminum sheet metal. Theshells respective flange regions 16 and enclose ahollow space 18 between them. Areinforcement element 20 is arranged in thehollow space 18. This comprises abasic body 22 made from a fiber-reinforced plastic, into whichangled metal strips 24 are inserted. Themetal strips 24 extend into theflange regions 16 with theirend regions 26 and are there connected to theinner shell 12 and theouter shell 14. - As well as reinforcement fibers made from plastic, the
basic body 22 comprises further additionalmetallic reinforcement fibers 28. Thebasic body 22 of thereinforcement part 20 is formed to be S-shaped and comprises acentral part 30 as well aslateral arms arms inner walls outer shell 12 and theinner shell 14, such that a particularly good support effect is achieved and flapping is avoided. - As is clear in the side view of the
reinforcement part 20 inFIG. 2 , themetal strips 24 extend over the entire length of thereinforcement part 20 and are therefore also connected to theflanges 16 over the entire length thereof. Thebasic body 22, made from fiber-reinforced plastic, has a structure made fromreinforcement ribs 40, which are not all referred to for the sake of the overview. Furthermore, abulge 42 extends over the entire length of thebasic body 22, which likewise serves for further strengthening. - Due to the
sheet metal structures 24, a conventional joining ofouter shell 12,inner shell 14 and strengtheningpart 20 is enabled, which can occur, for example, by welding, soldering, riveting or clinching. Releasable connection techniques, such as, for example, screwing, can also be used. Themetallic reinforcement 28 can likewise be joined to thesheet metal 24 separately, for example by welding or soldering. In particular, metal wires, nets, fabrics, webs, cables, bands, rovings or strips can be used as ametallic reinforcement 28. - For the production of the
reinforcement element 20, known methods of fiber composite technology can be used. The reinforcement fibers andmetallic reinforcement elements 28 can, for example, be overmolded simply with plastic or a hybrid mass made from short fiber-reinforced plastic. Sheet molding compound (SMC) or resin transfer molding (RTM) methods can also be used. Herein, themetal strips 24 can be integrated immediately, directly into the plastic matrix, such that these can be overmolded in the same procedure and in the same tool as the fiber inserts. For this purpose, thefiber reinforcement 28 can already be fixedly connected to themetal strips 24 before the overmolding. Furthermore, in themetal strips 24, further holes, undercuts or similar can be provided, which ensure a fixed interlocking between themetal strips 24 and the plastic matrix of thebasic body 22. Themetal strips 24 can obviously also be integrated into the SMC or RTM process as prepregs or preforms together with thefiber insert 28. Therein, the fixed connection offiber inserts 28 andmetal strips 24 can be required, if necessary, in the prepreg formation, whilst this is not necessary in the formation of a preform, as there the melted and solidifying matrix mass fixedly encloses the metal strips in the consolidation. - Overall, such a
column 10 is created, which manages with particularly few individual components, integrates particularly simply, stably and cost-effectively into steel/aluminum shells in a fiber composite hybrid reinforcement, and enables the use of conventional joining techniques. Compared to conventional reinforcements made from steel or aluminum, a particularly high E-module can be achieved using thereinforcement element 20, which, with acolumn 10, in turn leads to an improved utilization of material and a particularly high weight reduction and a low CO2 emission of the motor vehicle connected to this. - The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
